In which U.S. city did Art Ingels create the first motorized go-kart?

Art Ingels created the first motorized go-kart in Los Angeles.

The machine was assembled in 1956 in the Los Angeles area, commonly identified more specifically with Echo Park and the nearby Southern California racing scene. Ingels, a fabricator at Kurtis Kraft, built a low tubular frame and combined it with a small surplus lawnmower-style engine. The result was a basic, lightweight vehicle intended for informal racing and experimentation.

The kart’s early public testing helped spread the idea. Enthusiasts gathered at the Rose Bowl parking lot in Pasadena, where the unusual little racers attracted attention and inspired others to build their own. Pasadena is a separate city, so it can appear in accounts of the first kart’s history, but the question asks for the broader city associated with Ingels’ creation: Los Angeles.

Another frequent confusion involves Indianapolis. Ingels worked on race cars associated with the Indianapolis racing world, but the first go-kart itself was built in Southern California, not at Indianapolis Motor Speedway.
